Figure 5 AW338XX typical application circuit(using external OVP threshold)

Notice for Typical Application Circuits:

When the default OVP threshold is used, connect OVLO pin to GND directly or through a 0

Ω resistor. OVLO

pin cannot be left floating.

If R1 and R2 are used to adjust the OVP threshold, in order to speed up the OVP response, R1 + R2 < 100k

is recommended. It is better to use 1% precision resistors to improve the OVP threshold precision.

CIN = 0.1

μF is recommended for typical application, larger CIN is also acceptable. The rated voltage of CIN

should be larger than the TVS maximum clamping voltage, if no TVS is applied and only AW338XX is used,

the rated voltage of CIN should be 50V.

COUT = 1

μF is recommended for typical application, larger COUT is also acceptable. The rated voltage of

COUT should be larger than the OVP threshold. For example, if the OVP threshold is 6.8V, the rated voltage

of COUT should be 10V or higher.
